GYRATORY BOLTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 671,347, dated April 2,1901. Application filed April 18, 1898. Serial No. 677,995. (No model.)

To all 1,071,071@ t may concern/ Be it known that I, HARVEY CHRISTOPHERMALSNESS, of the city of Stratford, in the county of Perth and Provinceof Ontario, Canada, have invented certain new and useful Improvements inGyratory Boltin g-Machines, of which the following is a specification.

My invention relates to that class of sifting and bolting machines fortreatingr and separating ground grain and like substances in which oneor more inclined sieves are arranged in a sieve-box and are providedwith means for producinga horizontal rota ryswinging motion of the boxwithout actual rotation about its axis. 'Y

The object of my invention is to so construct the machine as to renderit simple and convenient in operation, highly efficient in action,and-capable of handling separately any number of separations of thedifferent grades of material at one and the same time in the smallestspace; and the invention consists in the construction, arrangement, andcombinations of parts, as hereinafter described and then definitelyclaimed.

In the accompanying drawings, Figure l is a perspective view of myinvention, showing the sieve-box mounted in a suitable supporting-frame,a portion of the box being broken away to expose the interiorconstruction. Fig. 2 is a sectional elevation of my machine through thelong way of the sieve-box. Fig. 3 is a sectional plan of my machine.Fig. 4 is a sectional elevation of my machine through the narrow Way ofthe sieve-box. Fig. 5 is an exterior plan View of the machine. Fig. 6 isa diagram of separations, showing the improved system for use inflourmilling. Fig. 7 is a projection of the bolting-surface in themachine corresponding with the diagram shown in Fig. 6. Fig. 8 is aperspective detail of three of the sieves, showing thecontinuous-circuit travel of the stock. Fig. 9 is a perspective detailshowing an adjustable cut-of. FigflO is a sectional elevation showing anadjustment to control the tension of the brush against the sieves. Figs.1l, l2, and 13 are details which will be referred to hereinafter.

In the drawings like letters of reference indicate corresponding partsin the different igures.

A is a stout hard-wood frame for the support of the sieve-box B, whichis suitably driven, as hereinafter described.

C represents rods formed with right and left hand threaded ends andsquared central portions a, by which they may be turned. The ends ofthese rods C are screwed into stirrups D, connected by ball-and-socketjoints E with the top of the frame and the lower side of thesieve-box,as shown. By adjusting the rods the hang of the sieve-box maybe accurately adjusted and its weight equalized while in motion. Thesieve-box is preferably constructed of light pine and is partitioned offat the ends and divided into a number of spouts F. The partitions G,dividing the 'spouts from the screens, form substantially the end of thesieve-box so far as the sieves are concerned. These partit-ions G aregrooved to receive the two outside selies of inclined sieves I J and thetwo inside series of oppositel -inclined sieves I J. It will be seenthat these are up ica e a each side of the machine, each half formingpractically an entirely separate apparatus. The two parts are separatedby the partitions H.

K represents the sides of the sieve-box, which are suitably held inposition by rods K', extending through them from the partitions H andprovided with suitable nuts by means of which the sides can be securelyclamped in position.

Thescreens at each side of the machine are separated by the partition L,which is preferably made so that it can be readily removed to gainaccess to the inner screens.

Reference to Figs. l, 2, 4, and 8 will show that the tail ends of eachof the sieves of the series I I are substantially on a level with thehead of the corresponding sieve upon the opposite side of the partition.The same holds good of the sieves of the series J J'.

Through thepartition L at the tail end of any desired sieve I form anopening b, so that when the apparatus is in motion, as hereinafterdescribed, the stock will pass freely from the tail end of the sieve inquestion onto the head of the opposite and oppositely-inclined sieve onthe other side of the partition. When the stock in traveling over thefirst sieve reaches the end of the same, the circular motion of themachine being, for instance,

TCO

the tops of the partitionsG, through whichV with the sun would cause thestock to d escribe half-circles in a direction against .the sun alongthe partition G at the foot of the sieve, the inclined surface keepingthe stock against said partition and compelling it to go forward till itpasses through the opening and travels down the sieve upon the oppositeside of the partition, as indicated by arrows. Thus a continuous-circuittravel is given the stock over an inclined cloth surface of squaresieves without losing fall or heightin passins the Stock frQm cassierert0 tbe'other. It is well known that stock may be passed from the tailend of one sieve onto the head' of an oppositely-inclined sieve directlybelow it; but in such a case there is a great waste of space, and thecapacity of such a machine is therefore very limited.

It will be seen that in Fig. S the openings b are so arranged that thestock travels continuously over three sieves before tailing out at theopening c into one of the spouts at the end of the sieve-box. Theopenings l) can be so arranged as to permit of the stock passing. overas many of the sieves as may be desired. A reference to Figs. 2, 4, and7 will show that the sieves of the second series of both the inner andouter sieves are principally blanks to catch and tail olf thestock-passing through the sieves of the first series.

Wherever necessary, curved guidgswrlf are placed on th ieves to directthe stock tothe variou. openings. istributingars may almmthe sieves,onto which the openings b discharge. (See Figs. l and 8.)

I do not claim any special novelty in the means of introducing the stockinto the sieveboX and withdrawing it therefrom. Whenever it may bedesired, any one of the spoutsi F may be caused to communicate with anydesired sieve by means of an opening c' (see Fig. l) above the curvedfalse -bottom d in the chute, so that stock may be thereby conveyed tothe head of th'e sieve. In the same way tailings may be removed from anyde=4 sired sieve by means of an opening such as already referred t0.

Whenever it be desired to remove from the machine thestock which haspassed throughl one or more sieves, I insert below them a blank sieve M,which is made to tail off into one of the spouts F. I show in thedrawings of the machine only so much of the spouting as is necessary toillustrate the principles of operation. By reference to Figs. 6 and 7 apractical miller will readily understand how` the machine may bearrangedfora complete: system of separations and how the spouting may bearranged to suit the same. 1 N and O' are the top and bottom, respectively, of the sieve-box, in which are formed` holes with whichcommunicate the flexibleI bags O. Ledges P-are preferably formed atV thestock may be dropped onto thetop sieves or from which it may be shakeninto the spouts F. The bottom ofthe machine is also `off to any desiredpoint.

4,totake up wear. `the cranked driving-shaft S, carried in suit- -ablebearings T on the frame A. Secured lto the shaft S are thebalance-wheels U, procurately adjusted.v

provided with suitable openings -with whichl are connected the iiexiblebags Q.

As it is desirable to have the operation of the machine entirely undercontrol, it is necessary to provide an adjustable cut-off, such as shownin Fig. 9. Below one of the sieves I place a sieve-frame provided with aplate q, movable in the guides r. The lower end of this plate overlapsthe stationary plate s. In order to.clamp the plate q in any desiredposition, I provide the bolt t, which passes through the plateandthrough a slot formed in the stationary bar a. When the plate ismoved, by tightening the bolt and nut the plate may be securely held. Atthe lower end of the sieve above may be placed a section of wireor-cloth of muchV coarser mesh than the general surface of the sieve.Thus material passing through the head of the sieve may be allowed todrop through to a lower sieve, while more or less of the materialpassing through the center and coarse part of the sieve may beintercepted and tailed The coarse-mesh portion at the tail of the sievepermits all but `the coarsest tailings to fall through onto theIadjustable cut-off to be discharged separately to any desired point.

Connected to the top and bottom of the sieve-box are the eccentric'boxesR, preferably provided with brass linings adjustable Through these boxesruns vided with adjustable balance-weights e, so that the balance of themachine may be ac- The shaft is preferably `driven by a pulley V,connected thereto beglow the lower balance-wheel.

The means provided for oiling the bearings v,is novel, consisting inplacing a large sight- :feed lubricator f over the top of thedrivingshaft. This lubricator is set to feed the required amount of oilwhich follows the shaft down to the bearings through ducts provided vinthe balance-wheels to the bearings on the sieve -IboX and through to:the step-bearing upon the frame.

On opposite sides of the sieve-box I place a series of pulleys gand passaround themA an endless cordA h, which is taken back to one side of themachine and passed around the pulleys z'. The pulleys g are so locatedthat 'a portionofthe cord is below each of the sie' Connected t9 afpmdWerft@ f* tail inFigs. 8 and l0.) This'ib'fus'lhas a stiff `rod laconnected to it centrally, tothe ends of which the cord h is connected.This rod tends always to maintain thebrush at right angles to thedirection of travel. vThe back ofthe brush] rests upon theguides Z,which are vertically movable in the supports m by fmeans of theset-screws n. Thus the guides 'Z may be set to give the brush anydesired degree of tension against the lower side ofthe IOO IIO

sieve above it. By reciprocating the portion of the cord between thepulleys 0l it is evident that the brushes will be caused to travelalternately from end to end of the sieves, thus always keeping the clothclean, which is something that has never before been accom plished inany rotary machine of this nature.

0 (see Figs. l, 2, and 12, and particularly` Fig. l2) is a castingcarrying a swivel adapted to engage with the right and left hand threadformed upon the vertical shaft p. By the rotation of this shaft theswivel and casting are given a reciprocating motion up and down the saidshaft, so as to suitably operate the cord h. This shaft has suitablebearings on the frame A and is driven by suitable driving pulleys andbelt from the driving-shaft S. As the machine is provided with four setsof sieves, four cords h are used and the casting o is provided with across-bar to which the various cords are connected, as shown in Fig. 1.

From the above description `and the accompanying drawings it will beseen that I have devised a machine for the intended purpose which isvery efficient and easily operated and one that will be found desirableand convenient in actual operation.

It is evident that the exterior appearance in the details ofconstruction could be materially changed without departing from thespirit of my invention.` The frame, for instance, may be eitherindependent, as shown, or the sieve-box may be suspended from part ofthe building.
